1.Description
BQ, NQ, HQ, and PQ diamond core bits form a complete range of
wireline coring tools, engineered to deliver precise,
high-integrity rock samples across diverse drilling scenarios. From
shallow geological surveys to deep mineral exploration, these bits
are designed to match standard wireline coring systems, ensuring
compatibility with most industry-leading rigs and core barrels
while maintaining exceptional performance in formations ranging
from soft soil to ultra-hard rock.
Key Specifications, Sizes & Applications
Each model is tailored to specific depth ranges and formation
types, with standardized dimensions to ensure seamless integration
into drilling operations:
BQ:
Bit diameter: 43.0mm
Compatible core barrel: BQ
Optimal drilling depth: ≤200 meters
Primary applications: Shallow geological mapping, environmental
soil sampling, and small-scale foundation testing. Excels in soft
to medium formations such as clay, sand, and weakly cemented
sandstone, providing intact cores for preliminary geochemical
analysis.
NQ:
Bit diameter: 75.7mm
Compatible core barrel: NQ
Optimal drilling depth: 200–500 meters
Primary applications: Versatile mid-range coring for mineral
prospecting (coal, iron ore), groundwater exploration, and civil
engineering foundation detection. Performs reliably in medium-hard
formations like limestone, shale, and low-grade metamorphic rock.
HQ:
Bit diameter: 96.0mm
Compatible core barrel: HQ
Optimal drilling depth: 300–800 meters
Primary applications: Hard rock drilling for mining exploration
(precious metals, industrial minerals), tunnel construction
surveys, and deep borehole logging. Efficiently cores through
granite, gneiss, and moderately abrasive formations while
maintaining high core integrity.
PQ:
Bit diameter: 122.6mm
Compatible core barrel: PQ
Optimal drilling depth: ≥500 meters
Primary applications: Ultra-deep drilling in ultra-hard or
fractured formations such as basalt, quartzite, and deep-seated
igneous rock. Critical for geothermal well development, deep
mineral exploration, and large-scale infrastructure projects
requiring large-diameter core samples.
